Answer 1

Correct choice is (b) False

Easiest explanation: Fixed cores and moving cores, both of metal are used in this method of casting. Moving cores are not parallel with the die movement and hence are to be removed before the casting is ejected from the die. And other is fixed cores, which are fixed to the die halves and parallel to the die movement.
